World Scientists' Warning to Humanity (1992)
Some 1,700 of the world's leading scientists, including the majority of Nobel laureates in the sciences, issued this appeal in November 1992. The World Scientists' Warning to Humanity was written and spearheaded by the late Henry Kendall, former chair of UCS's board of directors.
INTRODUCTION
Human beings and the natural world are on a collision course. Human activities inflict harsh and often irreversible damage on the environment and on critical resources. If not checked, many of our current practices put at serious risk the future that we wish for human society and the plant and animal kingdoms, and may so alter the living world that it will be unable to sustain life in the manner that we know. Fundamental changes are urgent if we are to avoid the collision our present course will bring about.
Over 1,500 members of national, regional, and international
science academies have signed the Warning. Sixtynine
nations from all parts of Earth are represented, including
each of the twelve most populous nations and the nineteen
largest economic powers. The full list includes a majority
of the Nobel laureates in the sciences. Awards and
institutional affiliations are listed for the purpose of
identification only. The Nobel Prize in medicine is for
physiology or medicine.
